The closest my vocabulary gets to a specifically second person plural pronoun. It, as well as 'you guys', which I would accept in my dialect but don't say, is of a peculiar structure: the 'you' isn't simply the determiner function before a common noun (as in 'you students'), because (i) we freely say 'we students' but not *'we lot', and (ii) determiner 'you' seems to require a plural noun, not a group word: *'you group', *'you crowd'.

However, although 'you lot' has a certain pronoun-like quality, the 'lot' is entirely optional. A true pronoun would be fused and grammatically controlled like 'yourselves', which is in most positions not interchangeable with 'you'.
